Creates a StringKeyGenerator that hex-encodes SecureRandom keys of 8 bytes in length.

Usage

From source file:io.stallion.utils.Encrypter.java

public static String encryptString(String password, String value) {
    String salt = KeyGenerators.string().generateKey();
    SecretKeySpec skeySpec = makeKeySpec(password, salt);
    byte[] iv = KeyGenerators.secureRandom(16).generateKey();
    String ivString = Hex.encodeHexString(iv);

    try {//from ww w.j a  v  a  2s  .  c om
        Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec, new GCMParameterSpec(128, iv));
        /*
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec,
        new IvParameterSpec(iv));
        */

        byte[] encrypted = cipher.doFinal(value.getBytes(Charset.forName("UTF-8")));
        String s = StringUtils.strip(new Base32().encodeAsString(encrypted), "=").toLowerCase();
        // Strip line breaks
        s = salt + ivString + s.replaceAll("(\\n|\\r)", "");
        return s;
    } catch (Exception e) {
        throw new RuntimeException(e);
